Facts for Using Infrared Thermometer Gun in Temperature Screening

Facts for Using Infrared Thermometer Gun in Temperature Screening

The best infrared thermometer for body temperature is any laser thermometer manufactured by a reliable company with lots of experience in measuring temperatures. Your decision should be based on fair prices charged by the manufacturer to avoid the problems of price gouging that are affecting many supplies and products during the Coronavirus scare.

Thermometer gun has become increasingly popular for taking surface temperatures from a distance – there’s no need to come into physical contact with the item or person. The use of thermometer guns has soared since the Coronavirus threat spread to western countries. Many businesses and public institutions use thermometer guns to screen large numbers of people to detect those who might be sick and running a temperature.


Why Thermometer Guns are Considered as Inaccurate and Unreliable

The question arises whether you can take body temperature with an infrared thermometer, and you can with a high-quality medical infrared thermometer under certain conditions. Problems arise, however, especially during the Coronavirus scare. Thermometer guns can be highly inaccurate, mostly because of operator mistakes.

Inaccuracies include operating errors and misinterpretations of readings. People who don’t know how to use thermometers can get inaccurate readings for a number of different reasons. These include:

  1. Not Following Instructions
    Thermometer guns must be used at the proper distance – not too close or too far away – to get an accurate reading.
  2. Only Accurate for Reading Surface Temps
    The thermometer guns only measure the surface temperature of the skin. That can fluctuate for many reasons, and the guns don’t measure internal temperature like a probe.
  3. Needs Skilled Adjustment
    A non-contact thermometer needs to be adjusted to read the temperatures of different surfaces.
  4. Subject to Environmental Influences
    Frost, rain and other conditions can affect surface temperatures. Rapid changes in the ambient temperature of a room can also skew readings. Electromagnetic field and radio frequency interference can cause inaccurate readings.
  5. Not Transparent to Glass and Other Substances
    Thermometer guns can’t read temperatures through the glass and other transparent materials. Instead, they make the surface temperature of the barrier instead of the target.

For COVID-19 Coronavirus, How Well Do Thermometer Guns Work?

The thermometer guns can be very useful for screening crowds at a public event, hotel, school, hospital, airport and other places where people gather. You can get a quick reading and identify someone who might be sick with the COVID-19 Coronavirus. However, there are many reasons why an experienced operator can get inaccurate readings. A restaurant server, chosen at random to screen customers, could cause unnecessary worry, ostracize a perfectly healthy person and even lead to gossip, quarantine and other treatment measures that aren’t needed. It’s also important to ask questions to determine if there are other symptoms of the virus if you get a high reading.

The thermometers work well if you choose a high-quality unit from a reliable company like ThermoPro and an operator who follows the recommended best practices. The advantages of using a thermometer gun include:

  1. Ability to monitor the temperature without touching a contagious person
  2. Can be used for various applications
  3. Lightweight, compact and easy to use
  4. Fast scanning of large crowds
  5. An important resource for many places like airports, hospitals, schools, etc.
  6. Great for taking temperatures of uncooperative targets – such as infants, pets, small children, etc.

The disadvantages of using a thermometer gun include:

  1. Inaccurate readings caused by operator error
  2. Unnoticed environmental conditions that skew readings
  3. Likelihood of causing false readings that can greatly inconvenience people
  4. Possible quarantining of people who aren’t sick
  5. Requires a learning curve for inexperienced operators

Proper Ways to Use a Thermometer Gun

The best infrared thermometer for body temperature is one that’s manufactured by a company with experience in manufacturing accurate thermometers. It’s also best to buy directly from the manufacturer and avoid the price gouging that many people face when buying sanitary supplies and other products to combat the risk of contracting Coronavirus.

For example, a thermometer from ThermoPro is reasonably priced, highly accurate and can be set specifically for taking body temperatures and even testing the surface temps of cooked foods. The following steps show how to use a ThermoPro thermometer gun correctly:

  1. Set the Reading to Fahrenheit or Celsius
    You can move the toggle switch easily to change your measurement to Fahrenheit or Celsius.
  2. Set the Measurement Unit
    Choose what kind of reading you’re doing – food, body temperature, etc.
  3. Turn on the Laser Gun
    The power button turns on the gun for use.
  4. Aim the Gun
    Aim the gun to the object or person. Make sure there is nothing blocking the gun and target.
  5. Get Close
    Get close to the object or person – between one and two feet.
  6. Pull the Trigger
    Pulling the trigger gives an instant infrared reading on the gun’s display.

The Right Environment to Use a Thermometer Gun

According to the temperature-taking experts at ThermoPro.com, thermometer guns can only be used accurately under the right environmental conditions. The gun only measures surface temperatures and not more accurate internal temperatures that apply to food and body temperature. The right environments for using a thermometer gun include:

  1. Controlled or Mild Environments
    The guns work accurately where there are little or no moisture, smoke, dust, frost, and particles in the air.
  2. Indoor Environments
    The guns work best in areas free of electromagnetic equipment, radio frequencies, and high or low internal temperatures.
  3. Close Operation
    You must be close to what you’re measuring, be that food, body temperature or ambient heat from an oven or grill.
  4. Areas Free of Barriers
    The guns can’t “see” through glass, liquids, plastic or any transparent surface.
  5. Fast Temperature Changes
    Any area where the temperatures rise and fall quickly can throw off your readings.

Making Informed Decisions Instead of Panicking

Some people worry more about the closures, possible quarantines, and inconveniences of the world’s governments’ decisions to halt the spread of the Coronavirus. Panicking, hoarding sanitary supplies and paying inflated prices for thermometer guns and other supplies without knowing how to use them properly just increase the risks. You can rely on a reputable thermometer company with a great reputation for manufacturing accurate thermometers.

The ThermoPro TP30 Digital Infrared Thermometer Gun hits all the marks for accuracy, and it is the best infrared thermometer for body temperature and the surface temperature of foods. Learning how to use a non-contact infrared thermometer is easy with practice, the right thermometer gun and the ability to follow instructions.
